Specification of Letters Patent. illatentediAlpir. 6, 1920.

Application med July a. 1919. serial No. 308.4551 A To dit sv/'z om. 'it may concern:

Beit known .that I. Fai-:Damon MCLAUGH- ;Lzn', a .i-itiy/en of the -United States, residing at ("anton, in Vthe county of Fulton and 'tirate of Illinois, have invented certain new and usc-ful Imj'irovenn-nts in Antiskidding Arm-'ir for T ruck-Tires, of which the fol lowing is a specification.

This .invention relates to armored tire dev'ws. nd pertains esjlecially to a non-skid Aippliance for motor vehicle tires.

The object oi the invention to provide fiorrshidding device applicable to motor whirl tires` especially solid truck tires, and is er* @d v in such device simplicity of con- .et-#intimal for connecting the parts thereof, :ilse-'l a lliirding expeditious means for apply infr the device.

A. further object of the invention is to pra-vide a pairof chain-holding rings in two connected parts or halves of such novel and peculiar construction and relative arimign'fment as to permit one-half of the rings to be applied toa tire separate or independent of the other half, and to furnish special ffonstruction in the meeting ends of 'said halves affording a joint between said ends without attaching them, whereby said ends are made to have an overlapping engagement.

Other objects, advantages and improved results are attainable in the manufacture and ap lication of the invention as will hereinaiier appear.

n the accompanying drawings forming part of this application i Figure l is a sectional view of part of a truck wheel showing the application of the invention.

Fig. 2 is a perspective view of the chain rings' as connected for a tire.

Fig. 3 is a detail perspective view of one o1" the oil' set ends.

. The ysame reference characters denote the same parts throughout the several views of the drawings.

ln carrying outV my invention I employ two plate rings, each rintcr being divided into a pair of sections and fitting an automobile truck wheel 1, having the usual channeled rim 2 for holding a solid rubber tire 3, said rim having vflanges 4.

One pair of ring sections or halves as 5 and 6 correspond with the other pair of` sections 7 and 8, each section-` having an ear 9 formed on the inner periphery for bolts 10, which extend between the Wheel spokes and are provided with suitable nuts 11, for clamping the ringr sections to the Wheel rim 4. Each ring section has secured upon its outer face. as by rivets 12, tread chains 13 which extend iagonally over the tire, by reason of the rivets beingr placed not opposite but on an angle with respect to each other. This is an important feature in practical utility. These chains are permanently fixed to the ring sections so as to be in position when the rings are applied to a wheel, instead of having to be attached to the rings after the latter are in position.

An essential feature of my invention is in. the manner of connecting one pair of ring sections with the other pair so as to permit expansion and contraction of the rings wit-hout separating: or disconnectingr the sections thereof. This I accomplish by offsetting one end of each section so as to form a shoulder 14 and a space 15 in line with the offset section for the other or Hat end of the other sections. and forming an ear 16 projecting inwardl)T from each of the ends 5a for a bolt 17 which extends through the ears 1.6 and is provided with a suitable nut 1.8. The bolts l? like the bolts extend between the wheel spokes. so that the whole armor is clamped to the wheel rim, but the clamping bolts 18 may be adjusted to permit circular relative movement of the ring sections by reason of the overlapping,r slip ends without separating the sections. It will be observed that the fiat ends of the ring sections are supported by the bolts 18 so as to prevent any possibility of sagging of the slip joints,

Obviously the -slipV joints permit the ring sections to adj ust themselves so as to make the chains fit tightly over a tire without separating,r the ring sections or leaving` an opening therebetween, and thev shoulders form abutments for the fiatuends of the sections.

It will` be understood that the rings may be made in various sizes.Y material and vwidths as desired, and that the chains may be decreased and multiplied as desired. ior

as occasion mav demand without depa ting from the invention.

Having thus described my invention what Q 1,ase.aes

I claim asnew and desire to secure by Letters Patent is: A

In a deviceyqf the character described, a pair of yplate rings' each being divided into a pair of sections having overlapping ends forming La slip joint, one of said ends being off set and having a shoulder for free abutment of the other end so as to limit contraction and permit expansion of the rings,

ear extensions'of the off sets projecting in- 10 wardly from the rings in op osite pairs, and u bolt extending throughy tge eers.

-In witness whereof I hereunto set my hand in the resence of two witnesses.
